A SKU is one style, in one color, in one size — the thing a customer adds to a cart. Multiply those three together and a modest-looking collection turns into hundreds of them, each holding almost no stock. This shows you the number before you commit the money.
Your collection
What that means
This spreads too thin to sell.
Your XS is 1.7 units per colorway — you can’t stock a size with that. Your middle sizes run out in the first week and you’re left holding the ends, which is how brands end up with inventory that never moves. Cut styles or colors before you cut quantity.
Every SKU in your run
One square is one style, in one color, in one size. 90 squares, 500 units between them.
Size split is a standard retail curve — 5% XS, 15% S, 30% M, 30% L, 15% XL, 5% XXL. Adjust for your audience; menswear skews larger, and a fitted womenswear line skews smaller. Healthy depth here is 12+ units per SKU, which is a judgement call rather than a law: it’s roughly the point where the middle sizes last long enough to learn anything from.
